[PATCH v2] arm64/prefetch: fix a -Wtype-limits warning

The commit d5370f754875 ("arm64: prefetch: add alternative pattern for CPUs without a prefetcher") introduced MIDR_IS_CPU_MODEL_RANGE() to be used in has_no_hw_prefetch() with rv_min=0 which generates a compilation warning from GCC, In file included from ./arch/arm64/include/asm/cache.h:8,
